Free-to-play Android games aren't difficult to come by, but this one has a little more going for it than mere affordability and simple play mechanics. CastleStorm made quite the name for itself on consoles this past fall, and now a touch-friendly adaptation is hitting Android as a private beta. The game combines tower defense with destructive physics, crisp graphics, fully voiced characters, and over 100 quests. The game isn't entirely free, as you need to spend money to get your hands on some in-game items, but with any luck, this won't hinder gameplay too much.

One of the most common complaints against Google's Play Store is the lack of certain content or functionality in countries outside the US. Google has been making progress in expanding access to other corners of the globe, though. You may remember, for example, that Play Books hit France just last month after Play Movies opened for the French in March and for Spain in June.

Today, Google (finally) brought Play Movie rentals to Germany, much to the delight of German users who have been asking for more Play content for quite some time.
